Rhubarb Bars

Robin, 31 January 2013, “Cheerful Things”

Crust:

¾ c plain/unbleached white flour

¼ c ground oatmeal:  whizz ordinary porridge oats in your blender or food processor.  You can also leave them whole, but in this case I like the texture better ground.

8 T lightly salted butter, room temperature, chopped up in preparation to being smushed into the flour and oatmeal

5-6T icing/confectioner’s sugar

1 egg white for glazing

Rhubarb:

1 large egg, room temperature

½ c caster/granulated sugar.  I know, caster is finer grained.  It’s not going to matter here.

¼ c dark brown sugar.  You can cut this down to 2 T and replace with 2 more T of the white.  I like dark brown sugar.

2-6 T ordinary white flour

4 c sliced rhubarb.  NOTE that both how thick you slice it and how much sugar and flour you use should vary with your rhubarb.  If it’s young and sweet and tender, cut big fat chunks and trim the sugar.  If the stalks look like the legs of sea monsters, slice more severely.  If it’s really wet, add more flour.  If it’s relatively dry, add less.

Optional:  1 tsp cinnamon

Or handful of fresh mint leaves, slightly shredded

If you have a food processor, you can make the pastry in it.  I have one but I still make pastry with a knife or the back of a spoon and one hand.†  Stir the flour and oatmeal and sugar (and cinnamon if you’re using it) together and then cut in the butter.  You want to rub it together till it’s reasonably homogenous but don’t suffer over it.  If you’re using unground oatmeal, add it last, after the pastry is mostly finished.  Press this into the bottom of an 8” square pan and glaze with the egg white.  The original recipe tells you to tip the pan back and forth.  My egg whites do not behave very helpfully.  I use either my fingers or a brush.  If you have any egg white left over—this should be a glaze, not a pond—tip it out.  Bake 350°F about 25 minutes.  Take it out and let cool.

Whisk the egg.  Whisk in the flour and sugar.  Stir in the rhubarb.  When the pastry is cool enough that you can pick the pan up in your bare hands, pour the rhubarb over, and put this in the oven for about an hour.  Cool COMPLETELY before cutting, and chances are, rhubarb being rhubarb, you’ll still be serving it in bowls.  Sprinkle mint leaves over, if you like mint leaves.
